Kreya▲90Hi HN! For over a year we've been working on Kreya. At first, it only supported gRPC, because the alternative tools (eg. BloomRPC) were very limited in their functionality. Since then, we have added many features, trying hard to keep the UI clean while still supporting advanced use cases. Yesterday, we released Kreya v1.8, which added support for REST! In our opinion, Kreya is a good alternative to the existing tools out there. Sure, it may not support all the features that Postman has. But we think that Kreya has some innovative approaches (eg. authentication or API importers) that users…

A few months ago, I benchmarked FastAPI on an i9 MacBook Pro. I couldn't believe my eyes. A primary REST endpoint to `sum` two integers took 6 milliseconds to evaluate. It is okay if you are targeting a server in another city, but it should be less when your client and server apps are running on the same machine. FastAPI would have bottleneck-ed the inference of our lightweight UForm neural networks recently trending on HN under the title "Beating OpenAI CLIP with 100x less data and compute". (Thank you all for the kind words!) So I wrote another library. It has been a while since I have…

Hi HN, I want to share with you an IntelliJ plugin I have developed and launched. Based on my own needs, I wanted a plugin that monitors my coding practices and gives me stats about them in order for me to improve on them. So, here is Kasama: An IDE plugin that works like a sport fitness tracker, gathering data on: - your coding sessions, i.e. how long are you active in the IDE and for which project - your activity in different modules, and how the activity is split between test code and prod code - your version control (git) interactions: how often you commit, the lifespan your branches,…

Kodus▲145Hey everyone, Just wanted to share a quick update we just launched at Kodus. For those who don’t know it yet, Kodus is a code review agent that runs directly in your team’s Git workflow (GitHub, GitLab, Bitbucket… and now Azure DevOps as well). It helps maintain code quality and consistency by analyzing each PR based on your team’s own rules and repository standards. Support for Azure had been a common request — so if your team uses it, you can now plug Kodus right into your workflow and give it a try. Docs: https://docs.kodus.io/how_to_use/en/overview Repo:…

Hey folks. I'm the author of kr8s. I’ve been working on kr8s for a while now and one of my core goals is to build a Python library for Kubernetes that is the most simple, readable and produces the most maintainable code. It should enable folks to write clean code when working with the Kubernetes API. If you're interested in how it compares with other libraries then check out [this post](https://jacobtomlinson.dev/posts/2023/comparison-of-kr8s-vs-...). Happy to answer any questions you might have in the comments here .

Kapeta is an end-to-end software development platform - which will allow you to design your system using a visual "living" systems diagram that'll generate boilerplate code as you design your system. Once you're happy with the architecture - you dive into the code and fill in the blanks - where the real value is. Once you're done with your system - simply publish and deploy it to take it online. Kapeta does all the heavy lifting of creating a Kubernetes cluster (Powered by GCP atm) and adding your software to it. This is just the beginning - and we're eager to add more features and providers…
